<P CLASS=para>
This class represents an Internet address, and is used when
creating <tt CLASS=literal>DatagramPacket</tt> or <tt CLASS=literal>Socket</tt> objects.
The class does
not have a public constructor function, but instead supports
three static methods which return one or more instances of
<tt CLASS=literal>InetAddress</tt>. <tt CLASS=literal>getLocalHost()</tt> returns an
<tt CLASS=literal>InetAddress</tt> for the local host. <tt CLASS=literal>getByName()</tt>
returns the <tt CLASS=literal>InetAddress</tt> of a host specified by
name. <tt CLASS=literal>getAllByName()</tt> returns an array of
<tt CLASS=literal>InetAddress</tt> that represents all of the available
addresses for a host specified by name. Instance methods
are <tt CLASS=literal>getHostName()</tt>, which returns the hostname of an
<tt CLASS=literal>InetAddress</tt>, and <tt CLASS=literal>getAddress()</tt>, which returns
the Internet IP address as an array of bytes, with the
highest-order byte as the first element of the array.
